   Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER

   Sammanfattning : Beyond Atlas is a Swedish private company with the goal of exploring the solar system with cheap and reliable spacecraft. Part of their maiden mission, Hugin, aims to demonstrate navigation, propulsion, and communication technology on a 3U CubeSat. LÄS MER

4. 3. Design, simulation, and testing of an electric propulsion cluster frame

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jeremy Bek; [2021]
   Nyckelord :Electric propulsion; gridded ion thruster; cluster; frame; thermal modelling; mechanical modelling; lumped-parameter model.; Elektrisk framdrivning; jonmotor; kluster; ram; termisk modellering; mekanisk modellering; klumpelementmodell.;

   Sammanfattning : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. LÄS MER

5. 4. Experimental Verification of BP-HiPIMS Thrusters

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

7. 5. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :David Villegas Prados; [2020]
   Nyckelord :Hallis; SPIS; EP; plume; hybrid PIC; Hall effect; HET; inside channel; plume expansion;

   Sammanfattning : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.
